Summary: PWN infection negatively affects gene expression in pine trees, but chalcone synthase genes and their related genes are proportional to changes in nematode populations and dominate a coexpression module enriched by genes highly correlated with the nematode population. Many genes closely related to chalcone synthase genes in the module are related to flavonoid biosynthesis, flavone and flavonol biosynthesis, and phenylpropanoid biosynthesis.

Summary: This study investigates the biocontrol potential of plant bacterial isolates against Fusarium oxysporum, Fusarium proliferatum, Fusarium culmorum, and Fusarium verticillioides. The isolates were identified as closely related to Bacillus subtilis (B1) and Bacillus tequilensis (B2-B4). All the bacterial isolates showed significant production of indole acetic acid (IAA), siderophores, and protease activity. In vitro antagonistic assays demonstrated that these isolates exhibited significant growth inhibition of the fungal mycelia, with F. proliferatum showing the highest inhibition.

Summary: The nematophagous fungal genus Esteya, a natural enemy of the pine wood nematode, was discovered in Florida with a new species named E. floridanum. It was found to kill the pine wood nematode in vitro and delay the death of two conifer trees in vivo, showing potential for biocontrol of pine wilt disease. This highlights the importance of studying pest organisms in their native regions.

Summary: This study aimed to isolate chitinolytic soil bacteria and determine their antagonism against root knot nematodes. Ten bacterial isolates showed significant antagonism by reducing mortality and egg hatch of the nematodes. In polyhouse trial, these isolates reduced the nematode populations and improved plant growth parameters. Whole-genome sequencing identified nine isolates as Bacillus spp. and one isolate as Paenibacillus sp. Overall, this study demonstrates the importance of chitinolytic bacterial strains in antagonizing root knot nematodes.

Summary: The study found that pubescent oak had significantly higher wood density than black pine, and stand mixture had a positive effect on wood density. Diameter at breast height had a positive impact on wood density in pubescent oak and a negative or neutral impact in black pine, the effects varying by bedrock and species.

Summary: The study demonstrates that the biocontrol agent K165 can confer inherited immune resistance to plants against Verticillium dahliae through histone acetylation. Offspring of plants treated with K165 exhibit primed immunity and enhanced lignification, paving the way for the use of biocontrol agents for establishing inheritable resistance to agronomically important pathogens.

Summary: In this study, a metagenomic approach was used to analyze the bacterial communities associated with several different strains of nematodes after killing their slug hosts. The results showed that these nematodes are not exclusively associated with one bacterium, but have variable and diverse bacterial communities. Additionally, the commercial strain of nematodes was found to have a specific association with Psychrobacter spp.

Summary: This study aims to examine the effects of Scots pine blister rust on the quality of Scots pine wood. The results show that the fungus has local effects and does not hinder the use of wood, especially the unaffected parts. The statistical analysis reveals that the fungus increases wood density but significantly diminishes its strength parameters. The structural properties of infected and healthy wood are similar and higher than the average values for Scots pine. The rust decreases wood homogeneity, affecting the quality and yield of timber.

Summary: Different studies have shown the importance of resin canal traits in the susceptibility of pine trees to the pine wood nematode. Resin canals facilitate the migration of the nematode and play a role in the accumulation of volatile terpenes in response to the pathogen. This research investigated the anatomical traits of constitutive resin canals in seven Pinus species with varying susceptibility to the nematode. The high-susceptible group had wider constitutive canals and higher xylem radial growth compared to the low-susceptible group. The results suggest that resin canal traits play a role in the susceptibility of Pinus spp. to the pine wood nematode.

Summary: Pine wilt disease caused by the nematode Bursaphelenchus xylophilus is highly damaging to East Asian pine forests. In this study, the response of PWN-resistant and -susceptible P. thunbergii to PWN inoculation was analyzed at the transcriptional level. Differential gene expression analysis revealed distinct strategies employed by the resistant and susceptible P. thunbergii in dealing with PWN infections. The results shed light on the mechanisms underlying resistance and susceptibility to PWN in P. thunbergii.

Summary: This study aimed to determine the contact angle of adhesives in eucalyptus and pine wood and its influence on bonding, as well as evaluate the wood-adhesive interface of glued joints with different adhesives and weights. Results showed that the viscosity of adhesives influenced the contact angle and wettability of the wood, and certain adhesives penetrated the wood, filling cell cavities adjacent to the main glue line.

Summary: The study found that different strains of the pine wood nematode (PWD) had different reactions to three strains of Bacillus cereus. Strains GD1 and GD2 significantly improved the survival and fecundity of the nematodes, while NJSZ-13 had the opposite effect. Inoculation experiments showed that the disease index of P. massoniana was AMA3 < a mixture of AMA3 and GD1 < a mixture of AMA3 and GD2. RNA-sequencing analysis revealed that genes sHsp21, Hsp70, and Hsp72 were up-regulated in the nematodes treated with GD1 and GD2, and pathways related to longevity regulation, MAPK signaling, glutathione metabolism, and cytochrome P450 metabolism were enriched.

Summary: The antibiofilm efficacy of six phorbaketals isolated from the Korean marine sponge Phorbas sp. was investigated, showing that phorbaketal B and phorbaketal C effectively inhibit biofilm formation by Staphylococcus aureus strains. Additionally, phorbaketal B also inhibits staphyloxanthin production, which protects microbes from reactive oxygen species, and both compounds inhibit the expression of biofilm-related genes hla and nuc1.
